I'm curious about how the two units in this product communicate with each other. For instance, if you're connected to the AP that's in "extender" mode, it will need to send your traffic to the other AP, then to the router and so on. From what I know, bandwidth could be halved in that case if the extender mode unit is using the same radio to receive and send traffic.

Does anyone know how it works in this regard? Does it use another band to "backhaul" traffic?
